DESCRIPTION:Color changing technology by PhotoChromic inks has been around the custom screen print and advertising industries for over a decade. The reason that this technology is still very popular among advertisers in custom screen print industry is the magical transformation of colors. This series of PhotoChromic colors come in basic colors such as red, blue, yellow, green and purple. When these colors are indoor and not exposed to ultraviolet light, they are almost colorless. However, when they are exposed to ultraviolet light (including sunlight) they will gradually turn into their own colors. The stronger light and longer expose duration, the higher the intensity of the colors. And of course there are limits as everything else, the colors will not increase their intensity after they reach their limits. PhotoChromic inks work the best with white t-shirts. However they also work with light color t-shirts such as natural. You would also want to take advantage of the magical color change by screen printing only a black and white image for the indoor image and leaves all the colors as PhotoChromic colors so they will only appear outdoor. In this way you optimize the color transformation between a black and white image and a full color image. We recommend PhotoChromic’s color changing technology for all outdoor events on t-shirts, sweatshirts and sportshirts. Imagine when your guests witness the magical color change. For sure that’s going to leave a long impression to them.
